The value of the acceleration due to gravity is not constant, decreasing with height above the surface of the Earth.What is the value of the acceleration due to gravity, in m s-2, in the ionosphere at a height 3.9x105 m above the Earth's surface? Give your answer to 3d.p.
A car accelerates at 5 m/s^2 for 8 seconds. The direction of its acceleration is due east. If its initial velocity was 7 m/s, also due east, what is its speed during this time interval? Round your answer to the two decimals. ________ A car accelerates at 7 m/s^2 for 2 seconds. The direction of its acceleration is due east (east = positive direction). If its initial velocity was 47 m/s, due west, what is its final velocity? Round your...
You are on a new planet and want to know the acceleration due to gravity. You take a ball and kick it at an angle of 21.0° at a speed of 21.5 m/s. If the ball is in the air for 14.6 s, what is the magnitude of the acceleration due to gravity?
You are on a planet with an unknown acceleration due to gravity. You drop an object from rest and a height 1.1 metres, and measure the final speed 5.6 m/s as the object hits the ground. Using the Principle of Conservation of Energy, calculate the magnitude of the acceleration due to gravity. Use 2 sf in your answer.
a particular planet has a radius of 1000km and the acceleration due to gravity at its surface is 4m/s^2. what is the acceleration due to gravity 1000km above its surface?
An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +15 m/s and measures a time of 20.0 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? See Diagram below: Show your work below:
An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +18.9 m/s and measures a time of 16.1 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? (positive = up, negative = down)
An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +17.9 m/s and measures a time of 22.0 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet? (positive = up, negative = down)
28. In a simple pendulum experiment for determination of acceleration due to gravity (g), time taken for 20 oscillations is measured by using a watch of 1 second least count. The mean value of time taken comes out to be 30 s. The length of pendulum is measured by using a meter scale of least count 1 mm and the value obtained is 55.0 cm. The percentage error in the determination of g is close to (a) 0.7% (b) 6.8%...
2. An aspiring juggler realizes that the acceleration due to gravity can be measured simply by comparing the time interval an object spends above a certain height when tossed vertically upwards to the total time it is in the air. Suppose she tosses a small ball vertically upwards and catches it a moment later (after a time ∆T elapses) at the same height it was released. In flight, the ball spends a time interval ∆t above a certain height H...
